[Benign symmetrical lipomatosis. A therapeutic dilemma?].

Benign symmetric lipomatosis (BSL), also known as Madelung's disease, is a rare condition and characterized by diffuse but painless growth of unencapsulated lipomas. A close correlation to alcohol and nicotine abuse, metabolic disturbances and malignant tumours have been observed. Surgical treatment is frequently followed by recurrence, nevertheless, it can yield satisfactory functional and cosmetic results. A case of BSL with uncommonly distributed tumors is reported.

[Replacement of Bauhin's valve with an end-to-end telescope anastomosis between the ileum and transverse colon. Experimental study in dogs].

A method of a telescope anastomosis for prevention of reflux was developed experimentally in dogs. After the resection of 40 cm of ileum and colon ascendens the ileal part was intussuscepted into the colon and fixed by seromuscular stiches. The vessels were left untouched. The intussuscepted part measured 3-4 cm. No ileus was observed in the 24 weeks. Glass balls of 1.2 cm diameter could pass through. Barium enema as well as air insufflation of different pressures showed no reflux. The serosa was covered pretty soon by a granular tissue and later on by normal mucosa.

Dynamics of the continent ileal bladder. An experimental study in dogs.

A continent ileal bladder was constructed in six dogs. The most important requirements for a continent ileal bladder as a reliable mechanism of continency and for prevention of back flow in the ureters could be achieved by two intussusception valves (nipples) of small bowel in opposite directions. The dynamics of these "nipple valves" were studied electromanometrically and radiologically. These experiments showed that these intussusception valves did not binder a free flow in the isoperistaltic direction and did prevent reflux in the antiperistaltic direction.

The Mallory-Weiss-syndrome: a clinical study of 20 cases.

This is an account of 20 cases of MWS, representing 8% of a series of 247 consecutive upper GI-bleedings. Men above 40 years and persons with severe concomitant disease are specially at risk. The prognosis is rather good, mortality from bleeding being 10%. Surgery should not be undertaken unless all conservative measures, including vasopressin infusion and even Sengstaken-Blakemore tube have been applied. The typical history, a hiatal hernia and alcohol intake are frequently missing. Neither studies of gastric acid secretion nor esophageal manometry disclosed new pathogenic aspects.

[Urinary continence after radical prostatectomy: the urodynamic proof of an anatomical hypothesis (author's transl)].

Prostatic carcinoma can be cured by a radical operation. In radical prostatectomy the whole so-called internal sphincter is removed. It is generally accepted and often proved that the external sphincter which is mostly somatically innervated cannot resume the funciton of continence. The postoperative urinary incontinence after radical prostatectomy is frequent and therefore the radical prostatectomy is not performed in many places. The problem of postoperative continence as well as incontinence after enucleation of the adenoma will be briefly discussed. In 1966, HUTCH described the so-called 'baseplate'. It is a bundle of smooth muscle fibers, circulary arranged around the bladder neck, which are also responsible for passive continence. He proposed that a certain sphincter function can be achieved by a tubular anastomosis of this anatomical substratum with the distal urethral stump. We were able to prove this anatomical hypothesis urodynamically. A specially constructed double-lumen perfusion catheter enabled us to register the so-called functional urethra profile and simultaneously register a new sphincter pressure wave in the transformed 'baseplate' which was responsible for the continence. We could observe this new sphincter region in all continent patients after radical prostatectomy whereas in the incontinent patients it was absent. Since 1972 we have employed the procedure proposed by HUTCH and have performed 20 radical prostatectomies. All these patients have been postoperatively completely continent. We are of the opinion that undue restraint concerning radical prostatectomy is no more justified.

Continent ileal bladder: an experimental study in dogs.

A method for constructing a continent ileal bladder has been tested in dogs. The requirements for a continent ileal bladder: continence, reservoir function, prevention of reflux, could be fulfilled in our experimental study.
